Vortech Research (improve experience growth for every loot) might be a tad overpowered. Got it along with Shrink Ray and loot duplication, and cooldown reduction after every crit, and I now have a 100% crit rate and fire 20 shots per second even before I start collecting gumballs.
After spending all that, my attack delay is now displaying as 0.00, my range is over 14, and my attacks pierce 10 enemies. I’m wondering if it’ll crash on night 20 the moment I start firing.
Update: didn’t crash, but it slowed down massively. By the end of night 20, I was level 1211.
